呢張圖係我第一個揾出黎,點解咁顯,系因為波音747系有四引擎
如佢只用兩個引擎,系飛到下不過好快失速咁解。
同埋其實仲有搞笑野,睇下第一張相,gay

咁不如你又講下點解你覺得係 747 唔係737, 767, 787?
同埋睇唔明咩"仲有搞笑野"
我知你好想寸TVB, 令人地覺得你好叻叻
但唔該講得明D可以嗎?
如果唔係我好難覺得你好叻叻

我估應該係咁
因為師兄睇到機頭果度有兩層,後面有一層,呢個係747既特色
而747應該係四引擎機,但係TBB既"疑似747 model" 只有兩個引擎.....
但係可能一般人對飛機無咁熟,所以唔係好清楚....

Any 747 model is capable of maintaining altitude up to about 27,000 feet at 90 percent of Maximum Takeoff Weight on any two engines. At lower weights, it can gain altitude.
The problem with any multi-engine airplane is that whatever caused the dead engine to die is also likely to get the remaining engine(s) before too long. So any engine-out situation is a critical situation. But a 747 flies about as well on 2 engines as (let's say) a Piper Aztec flies on one engine.
Have an enjoyable flight!
